Atmospheric Turbulence Simulation Experiment Based on Liquid Crystal Spatial Light Modulator

In this letter, an atmospheric turbulence simulation equipment based on a liquid crystal spatial light modulator is studied. We use fast Fourier transform to generate a phase screen, and uses the subharmonic method to compensate for its low-frequency components. The influence of different turbulence intensities on laser atmospheric transmission is successfully-demonstrated. The far-field spot and received power of Gaussian beams under simulated atmospheric turbulence with different intensity are measured through actual experiments. The experimental results show that the spot will be distorted, and the received power at the receiving end will be jittered in varying degrees.
